eerie...

Astroboffins have long been puzzled over the source of ultraluminous X-ray light in an arm of the Pinwheel Galaxy, just off the handle of the Big Dipper. While they could ascertain that the source, called ULX-1, was a system made up of a black hole and a star orbiting each other, they couldn't make the maths on its estimated mass and brightness add up.

... This BLACK HOLE just isn't BLACK AT ALL' snarl boffins


... a nearby black hole is not living up to its name at all by shining as brightly as it possibly can and showing scientists just how much more there is to learn about the astronomical phenomenon...


Also, our astronomical skies are not as unchanging as some religions would have us wish:

... 44-MEEELLION-star Hitchhikers Guide to the Galaxy

Anglo-Australian boffins have published a new survey of the northern sky that describes 44 million stellar objects and finds 250,000 have changed in the last 60 years...


All in colourful The Register irreverence!

I received a mail from the eLISA sponsoring group with this video. eLISA should be the new gravitational wave interferometer put in space by ESA, the European Space Agency, but it has been put in second rank after Athena, a new space X-ray telescope like NuSTAR.

Interesting read on Quantum entanglement:

http://www.sciencedaily.com/releases/2013/12/131203161549.htm

Recent research indicated that the characteristics of a wormhole are the same as if two black holes were entangled, then pulled apart. Even if the black holes were on opposite sides of the universe, the wormhole would connect them.

Not really about black holes but I didn't know where else to post this. Keeping an open mind with this one...

http://www.collective-evolution.com/2013/03/08/nasa-discovers-hidden-portals-in-earths-magnetic-field/

Mainstream science continues to grow further, but I often get confused between mainstream science, and science that is formed in the black budget world. It seems that information and discovery isn’t information and discovery without the type of ‘proof’ that the human race requires. Given that the human race requires, and has a certain criteria for ‘proof’, which has been taught to us by the academic world, information can easily be suppressed by concealing that ‘proof’. It’s no secret that the department of defence receives trillions of dollars that go unaccounted for and everything developed within the United States Air Force Space Agency remains classified. They are able to classify information for the sake of ‘national security’. Within the past few years, proof has been emerging for a number of phenomenon that would suggest a whole other scientific world that operates separately from mainstream science.

The Ley lines have a more spiritual and mystical connotation, no?

It is believed that, in ancient times, when Britain was far more densely forested, the country was criss-crossed by a network of straight-line travel routes, with prominent features of the landscape being used as navigation points.

New Age occultists claim ley lines are sources of power or energy. According to Robert T. Carroll, there is no evidence for this belief save the usual subjective certainty based on uncontrolled observations by untutored devotees. Nevertheless, advocates claim that the alleged energy may be related to magnetic fields. None of this has been scientifically verified.

It was the magnetic bit that caught me eye.

But at the end of your link ......

We have the technology to take ET home, anything you can imagine we already have the technology to do, but these technologies are locked up in black budget projects. It would take an act of God to ever get them out to benefit humanity – Ben Rich, Fmr CEO of LockHeed Skunk Works

OK, we can all see where they are coming from then ......

Meh, whether they really have the technology to bring ET home I very much doubt. But, with the billions of dollars the US government spends on R&D, and with only a part of that budget being unclassified its not such a stretch to say that the US has developed technology that the general public is still unaware off.

I mean, just in case you are interested, take a look at the unclassified budget for the US army, airforce and navy. Imagine what we could achieve if those kind of research budgets were made available for civilian research institutions.

The question as to who killed the radio star has finally been answered — it wasn’t killed, it committed suicide by changing itself into a black hole, just like many other radio stars. According to researchers in a December 20 press release, a certain kind of radio star turns off its radio transmission prior to going ka-bloo-ie, falling in upon itself, and changing into a black hole, while other radio stars turn into neutron stars.

Death By Black Hole In Small Galaxy?

A bright, long duration flare may be the first recorded event of a black hole destroying a star in a dwarf galaxy. The evidence comes from two independent studies using data from NASA’s Chandra X-ray Observatory and other telescopes.



A dwarf galaxy is located in the galaxy cluster Abell 1795.

Astronomers have discovered more than 100 small, dwarf galaxies with characteristics indicating that they harbor massive black holes feeding on surrounding gas; this could help resolve the question as to how black holes originated and grew in the early universe.

Astronomers have used NASA's Chandra X-ray Observatory and a suite of other telescopes to reveal one of the most powerful black holes known. The black hole has created enormous structures in the hot gas surrounding it and prevented trillions of stars from forming.

Hawking posted his paper on the arXiv preprint server on 22 January1. He titled it, whimsically, 'Information preservation and weather forecasting for black holes', and it has yet to pass peer review.


Interesting new theory. We will see.

That is truly fascinating! I have always liked the singularity theory, as you would have just one chunk of mass that has infinite density. It can vary in size, but it takes a lot of mass to equal a small amount of size do to the compression.

It's too bad, we can't perform direct measurements to confirm the nature of these gravitational collapses.

Probably mentioned it before (maybe even in this thread... heh) but I have no idea why physicists/cosmologists don't seem to consider GR time dilation in the collapse when an object nears its Schwarzchild radius/event horizon. From our perspective, it would asymptotically approach this size and never reach it, never mind collapse to a point of infinite density. Any "true" black holes inside their own event horizons would have to be primordial.

The non-primordial ones, then, could be 99.99% or whatever arbitrary closeness time permits of the way there and have all the effects that black holes are supposed to have on the space and matter around them, but could never attain that last fraction in finite time. No infinite densities thus no breakdown of physical laws to have to deal with.

Interesting indeed.

The popular press always seem to emphasize the 'singularity' view. Meanwhile, the effects upon time always seem to get ignored... Far too complicated for mere journalists to even dream about?

'Black holes' were initially described by astrophysicists/astronomers as "frozen stars" to emphasize the significance of the time effects... Hence my pet theory that we can never get to suffering a 'singularity' because there is never enough time for one to develop to become 'an infinity'... (Time in effect 'slows down' as viewed by an 'outside observer' as gravity increases.)

I've always been uneasy about what happens to material/radiation as it approaches the 'event horizon' from the outside or from the inside... Do you get to suffer an infinity of material/energy piling up across space and time in that region?...
